Mario and 3 friends each had 3/4 foot of rope. they needed 5 feet of rope altogether. do they have enough? explain.

They would not have enough because 3/4  times 4  would not equal 5...it would equal 3. Mario and his 3 friends each have 3/4 foot of rope. They needed 5 feet of rope altogether. Do they have enough rope? They would need 2 more feet of rope to complete the 5 feet. But they do not have enough feet of rope to make 5 feet. 

hope this helps :D
